We found this great black canvas that made the perfect sky for our painting. (If you don't have a black canvas, you can just paint a white one black.) We used masking tape to make the outline of the moon. Next, a Q-tip made the perfect craters with our glow-in-the-dark paint.

We continued using the Q-tip to create a sky of stars! It looked great once we removed our tape and even better in the dark. This has become almost like a night light for my children.
